What’s the difference between thinking about moving a body part, and actually moving a body part?
In: Biology
Let’s say I see some fireworks. My eyeballs tell my brain there’s cool stuff going on, and my brain lights up in a certain way. You could measure it, it’s all electric signals.
When I think about those fireworks, my brain mimics the way it lit up when those fireworks were really happening. It mimes the pattern that occurred when my eyes really were telling it fireworks were going off.
If you’re thinking about moving your arm, your brain is mimicking how it would feel if you really did move it. If you move it, the outside world makes you feel those things directly instead of through imagination.
